CVE-2024-2021Public exploitNetwork attack vector

Database disclosure via unvalidated delete identifiers

Published Feb 29, 2024 · Updated Aug 8, 2024

SQL injection in Netentsec NS-ASG Application Security Gateway 6.3 allows remote authenticated users to disclose database contents. The delete handler in /admin/list_localuser.php iterates attacker-controlled identifier-array values and inserts them into an SQL statement without validation or parameterization. Access to the administrative interface and a valid session are required; the public proof of concept demonstrates database-name disclosure.
